Air quality in Noida, Ghaziabad deteriorates
The air quality in Noida, Greater Noida and Ghaziabad deteriorated further on Sunday as the wind speed dropped in the afternoon, said the India Meteorological Department (IMD).
Noida turned warmer as the maximum temperature has increased by 3° Celsius in the past 24 hours, with weather analysts expecting the maximum temperature to soar by 2°-3° C after March 12.
“Due to a western disturbance, thunderstorms are expected in some isolated parts of the National Capital Region and the wind speed dropped in the afternoon, leading to an aggregation of the pollutant particles. Another western disturbance is expected from March 11. The NCR may not receive rainfall, but the western disturbance may have its effect in neighbouring Punjab and Haryana. The maximum temperature will remain under check till March 12,” said Kuldeep Srivastava, head of the IMD’s regional weather forecasting centre.
The wind speed may hover between 12 kmph and 15 kmph till March 12, Srivastava added.
